“…It is worth noting that the sensitivity to PE at the La 3+ doped TiO 2 NP decorated f-MWCNT modied GCE electrode was found to be 7.6690 mA mM À1 cm À1 ; which is comparable with values lately reported in the literature, such as YbM/f-CNFs/GCE (2.87 mA mM À1 cm À1 )6 and Pd NPs/BNHJ/GCE (2.33 mA mM À1 cm À1 ) 49. These comparison data further indicate that the La 3+ doped TiO 2 NP decorated f-MWCNT modied GCE electrode shows remarkable electrocatalytic action towards the reduction of PE, and these results are highly comparable with a previously reported PE sensor (Table1) 6,[50][51][52][53][54]. These observed data further indicate that the La 3+ doped TiO 2 NP decorated f-MWCNT modied GCE electrode shows very remarkable electrocatalytic action towards PE detection.3.2.5.…”

“…One example builds metallic phosphosulfides, resulting from electrocatalysis of hydrogen production. Paraoxon ethyl was detected and quantified using graphene-based NiFe bimetallic phosphosulfide nanocomposite with a rather low LOD of 3.7 10 −3 μM [ 150 ]. The synergistic effect of π-π stacking interactions has been emphasized between the aromatic moiety of paraoxon ethyl and graphene and the strong catalytic effect of NiFe phosphosulfide.…”

Electrochemical sensors play a significant role in detecting chemical ions, molecules, and pathogens in water and other applications. These sensors are sensitive, portable, fast, inexpensive, and suitable for online and in-situ measurements compared to other methods. They can provide the detection for any compound that can undergo certain transformations within a potential window. It enables applications in multiple ion detection, mainly since these sensors are primarily non-specific. In this paper, we provide a survey of electrochemical sensors for the detection of water contaminants, i.e., pesticides, nitrate, nitrite, phosphorus, water hardeners, disinfectant, and other emergent contaminants (phenol, estrogen, gallic acid etc.). We focus on the influence of surface modification of the working electrodes by carbon nanomaterials, metallic nanostructures, imprinted polymers and evaluate the corresponding sensing performance. Especially for pesticides, which are challenging and need special care, we highlight biosensors, such as enzymatic sensors, immunobiosensor, aptasensors, and biomimetic sensors. We discuss the sensors’ overall performance, especially concerning real-sample performance and the capability for actual field application.

“…A sensitive nonenzymatic electrochemical sensor was designed by Aghaie, Khanmohammadi, Hajian, Schmid, and Bagheri (2019) to determine paraoxon‐ethyl (PE), using the superior sensing layer of NiFe bimetallic phosphosulfide nanocomposite. This method gave excellent square wave voltammetric (SWV) signal and exhibited good linearity within 12.3–10,000 nmol/L, a low LOD of 3.7 nmol/L, and satisfactory reproducibility (RSD = 5.2%).…”

This paper reviews studies published in 2019, in the area of analytical techniques for determination of pesticides and herbicides. It should be noted that some of the reports summarized in this review are not directly related to but could potentially be used for water environment studies. Based on different methods, the literatures are organized into six sections, namely extraction methods, electrochemical techniques, spectrophotometric techniques, chemiluminescence and fluorescence methods, chromatographic and mass spectrometric techniques, and biochemical assays.
